Product Description:

The MDD025C-N-100-N2G-040GB1 is a motor for digital drive controllers produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Designed for rapid positioning tasks in industrial automation, the unit converts electrical drive commands into high-speed rotational motion that can be tightly synchronized with CNC or PLC control loops. Its compact frame and integrated feedback interface allow it to serve as the prime mover in small gantries, pick-and-place modules, and light mechanical handling axes.

At the mechanical interface, the centering diameter is 40 mm, and the rotor is balanced to the standard grade so coupling components can be mounted without additional trimming. Power and signal lines exit on Side B, and a keyed Connector housing simplifies quick exchange during maintenance. During stall conditions the stator can deliver 0.90 Nm of continuous torque, while in motion it reaches a rated speed of 10000 min⁻¹, giving it the high surface velocity needed for miniature spindles. A standard housing protects the windings, and the integrated shaft seal prevents coolant or lubricants from entering the bearing chamber.

Additional features define how the motor integrates with a drive axis. The built-in blocking brake applies 1.0 Nm of holding torque to secure vertical loads when power is removed. Position data is returned through resolver feedback, which gives absolute rotor angle information even during rapid accelerations. The frame conforms to motor size 025, and the length code C keeps overall depth to a minimum so it can be mounted close to adjacent axes. A plain shaft with a standard single-ended design accepts friction or collet couplings, and the omission of a secondary shaft end on side B eases sealing and reduces mass.
